The sorting apparatus includes: at least one set of sorting units 100;

the sorting unit 100 includes: a timing belt 110, where two ends of the timing belt are fixed; a trolley track 120 arranged in parallel with the timing belt 110; and a distribution trolley 130, where the distribution trolley 130 includes a driving assembly 140 and a guide assembly 131, the driving assembly 140 includes a driving motor 141 and a timing belt pulley 142, the driving motor 141 drives the timing belt pulley 142 to cooperate with the timing belt 110 and move along the timing belt 110; and the guide assembly 131 of the distribution trolley is configured to cooperate with the trolley track 120 to guide a moving direction of the distribution trolley 130.

In the present embodiment, in the sorting apparatus, one or more sets of sorting units may be arranged, and the sorting unit is the smallest unit to achieve the purpose of the present disclosure. Using one set of sorting units 100 as an example, the sorting unit includes the timing belt 110 whose two ends are fixed, the trolley track 120 and the distribution trolley 130. Here, the trolley track 120 is fixed with the timing belt, and the distribution trolley 130 further includes the driving assembly 140 and the guide assembly 131.

Specifically, the timing belt 110 is generally a belt-like object with a wire rope or glass fiber as a strong layer and covered with polyurethane or neoprene. Of course, the material and the shape of timing belt 110 may alternatively a material and a shape in the existing technology or in a future technology, which is not limited in the present disclosure.

The timing belt 110 cooperates with the timing belt pulley 142 to achieve the purpose of transmission. The cooperation approach may be selected from the existing technology or the future technology, such as meshing, snap-fitting and other connection approaches that achieve cooperation by friction; according to the different cooperation approaches, a timing belt 110 corresponding to the cooperation approach is selected. For example, when selecting the meshing approach, a timing belt having a side surface provided with a connection structure such as a tooth shape or a slot may be selected, such as a trapezoidal tooth timing belt, an arc tooth timing belt, or other timing belts in the existing technology or in the future technology. When selecting the snap-fitting approach, a timing belt having a side surface provided with a slot structure or a protruding structure may be selected. The present disclosure does not limit thereto.

Alternatively, the timing belt pulley 142 with a tooth-shaped structure on an outer periphery may be configured to cooperate with the timing belt 110 with a tooth-shaped structure. When the timing belt pulley 142 rotates, the tooth-shaped structure of the timing belt pulley may cooperate with the tooth-shaped structure of the timing belt 110, so that the timing belt pulley moves along the timing belt 110, and the distribution trolley 130 moves along the timing belt 110. In this way, the transmission structure is relatively simple, and it is not easy to make mistakes.

The two ends of the timing belt 110 may be fixed by using approaches in the existing technology or in the future technology. For example, a timing belt fixing plate, a timing belt buckle, a timing belt fixing pulley or other apparatuses may be configured to fix the timing belt 110. The two ends of the timing belt may be fixed by using the same or different apparatuses, which is not limited in the present disclosure. Alternatively, the two ends of the timing belt may be fixed by using the same apparatus, so as to facilitate fixing and maintenance of the fixing apparatus of the timing belt.

FIG. 1A exemplarily shows the cooperation approach between the timing belt and the timing belt pulley. The fixing approach of the two ends of the timing belt 110 is described below by using one end 111 of the timing belt 110 for convenience of description. The fixing apparatus of the timing belt 110 is a timing belt buckle, and the timing belt buckle and the timing belt 110 are connected by using a cooperation approach in the existing technology or in the future technology, which is not limited in the present disclosure. The other end of the timing belt may be fixed by using the same or different approach, detailed description thereof will be omitted. By arranging the timing belt 110 using this approach, the stability of the timing belt may be improved, the convenience of fixing and maintaining the timing belt may be improved, and the cost of fixing the timing belt may be reduced.
